This invention relates to improvements in fence structures and has particular reference to sectional precast and preferably concrete fences.

It is an object of the present invention to provide a concrete fence formed of precast posts and precast rails, to be assembled and tied together in a manner to provide a very rigid, exceptionally strong, highly ornamental and economical structure.

An object of the invention is to provide a novel form of post that comprises a plurality of identlcal precast hollow blocks that are notched on their top and bottom edges to provide a seat for the ends of the associated rails, the blocks adapted to be laid one upon the other and in number corresponding to the number of rails to be employed, with the entire post after assembly of the rails, adapted to be completely filled with concrete that is suitably reinforced, after which, a novel form of cap is applied thereto.

Another object of the invention resides in the novel type of fence rails that are L--shaped and adapted-to be seated at their ends in the post in amanner to dispose the rails at an angle, the rails being reinforced throughout their length with'the reinforcing projecting at either end and subsequently bent to any desired form to have interlocking connection with the adjacent end of a rail from the opposite side of the post and, at assembly of the posts and rails, the ends of the rails and their interlocking reinforcing to be encased in the concrete employed to fill the post.

'A further object of the invention is the provision of a fence having the above noted characteristics, whereby all the rails are angularly arranged transversely and at-such distance apart as to discourage sitting, climbing or otherwise using the structure for other than a fence.

Other novel features of construction will be readily apparent during the course of the following description, reference being had to the accompanying drawings, wherein has been illustrated a preferred example of the device and whereinlike characters of reference are 'employed to denote like parts throughout the several figures.

Referring to the drawings:

Figure '7, is an enlarged horizontal section through a completely assembled post and associated rails, taken on line 1'! of Figure 1 and,

Referring specifically t0 the drawings, the numeral 5 indicates a complete post as a whole and 6 indicates the several rails as a whole. A footing I of concrete is preferably employed, upon which the post is constructed.

Each fence post is formed of a plurality of identical precast concrete blocks 8, clearly illustrated in Figure 4. The blocks are hollow and open at their top and bottom, as shown and may be formed of any particular dimensions desirable. Each block is preferably rectangular and the upper edges of its longitudinal side walls are provided with identical V-shaped notches 9, equidistantly spaced from'the ends ofthe blocks. The apex of the notches extend slightly above the top edges of the block. while the terminal, ends of the V extend below the top edges of the block, forming right angled walls is having a length corresponding to the thickness of, thewalls of the rails, to be described. The lower longitudinal edges of the block 8 are identically notched, as at I l, of V-shape, with the. angles of the notches 9 and II being formed onan exact right angle. The notches H are equidistantly spaced from the ends of the block, as shown. The depth of the notches ll correspond to the combined transverse outer or top area of the rails 6., to be described, while the notches 9, terminating at the juncture of the walls Ill, corresponds to the combined transverse inner area of the rails 6. While the blocks 8'have been shown as having smooth outer walls, it'will be apparent that they can be cast with any desirable ornamentation.

=Each rail 6 is identical and is precast a conventional manner. The lengths of the rails may vary, but are identical in a particular spacing-of the posts'5. Each railis formed L-shaped, with each leg of the L being equal, providing legs 4 since to do so, a person must engage his foot with the relatively sharp apex of the rails and, when he attempts to climb, the instep of the foot will sharply engage the outer edges of the rails. The

i3, is indicated in Figure 8, wherein the ends are merely bent to a right angle, as at l5.

In the construction of the fence, the footings 1 I are first poured at the required distance apart, depending on the length of rail to be employed. After sufiicient setting, a block 3 is set upon each of the footings. Rails 6 are then laid upon the blocks, with their terminal ends projecting slightly into the opening of the blocks. It will be observed, that the rails rest within the notches 9 with the terminal edges of the walls I2 lying flush with the upper edges of the blocks and with the inner area of the rails conforming to the angle of the notches 9. In this position, the apex of the rails will be arranged upward. The positioning of the posts and the length of the rails permit the bent ends of the extended reinforcing l3 to interlock, as in Figure 7. After the lower flight ofrails have been laid, a second block 8 is engaged over the first block, with the notches H conforming to the angle of the rail and with the edges of the blocks beyond the notches in engagement. It is contemplated with this construction, that no mortar will be employed between the blocks. The progressive laying of the blocks and rails continues until the fence is of the desired height. Reinforcing rods I6 which have previously been embedded in the footings, project upward through the entire tier of blocks and, when the uppermost rail has been set in position, the entire hollow post is then filled with concrete, which action securely anchors the blocks together and also anchors the ends of the rails therein against displacement. While the filling of the post with concrete will in most cases securely anchor the rails against displacement, the interlocking ends of the reinforcing [3 also embedded in the concrete will sustain practically any pressure against the rails.

Since it is desirable to provide a finished or ornamental top to the post, a cap block l'l, Fig ure 5, has been provided. This block I! has been shown as V-shaped for ornamental purposes, but ,it will be apparent that other configurations may be employed. The block I! is likewise preferably cast of concrete and is provided in its bottom wall with a V-shaped notch I 8, conforming in size and angularity to the notches l l. The block I! is placed over the uppermost rail ends, resting upon the uppermost block 8, and is preferably cemented in position. The block i1, while being shown solid, may obviously be formed hollow.

It will be apparent, that a very novel and easily constructed fence has been provided. The several parts, including the blocks 8, rails 6 and cap block I! may be quickly and easily manufactured in considerable quantities and transported to the desired location. The blocks and rails are extremely cheap to manufacture and when assenibled they provide a fence that is exceptionally strong and ornamental. The arrangement of the rails at an angle discourage persons sittin thereon and will further discoura'geclimbing,

construction of such a fense is relatively cheaper than wood and much cheaper than a solid fence of concrete or concrete blocks. Further, the structure is permanent, from the standpoint of rotting and continual painting, as with wood fences. The fence further compares favorably with the conventional stock or cattle fences, since it is a permanent structure, needing no replacement and its strength will sustain without damage, any pressure placed thereon by cattle or the like.

It is to be understood, that the invention is not limited to the precise arrangement shown, but that changes in the shape, size and details of construction may be resorted to as fall within the spirit of the invention or the scope of the subjoined claims.
